I don't think we would be having this discussion if there was an appropriate description that we would use rather than lumping everything together as orthodox. We have "chassidish, ultra orthodox, etc. why not have a term " Culturally Orthodox Jews" or the like which would be an accurate description of those who have an affinity and identify with orthodox Jewishness on a cultural level while not yet being 100% on board in practice. I think this would eliminate a lot of the confusion and murkiness. And, let me say, I am really proud and excited that we have a wonderful Culturally Orthodox Jewish couple in Washington!
